Your letter is wonderful and warm. Someday your sister will regret the time she has wasted by shunning you. I'm sure her jehovah is pleased with her. Grrrr
So happy for you that you have found your soulmate. Congrats on the engagement and hooray for you for not rushing it on their account!
Also so glad you have a happy loving little doggie!! My dog is about the only one in my life that has never betrayed me.
Good luck to you - I have a letter to my mom in the mail too so we will be mail-box-checking together!
